1 Claim.

This invention relates to improvements in packing.

This invention relates to packing cords suitable for use in themillinery trade for making rolls in hats and the like. Such materialmust be light in weight and preferably must have a smooth outer surfaceso that it will not disflgure material stretched over it. It must beelastic and preferably inexpensive.

Heretofore such cords have been made of cotton or the like formed tocylindrical form and retained either by wrapping threads or by astitched fabric cover. It is expensive to apply stitched fabric coversand if Wrapping ythreads are employed the sheer materials used oyer thecord are disgured by the indentations and raised portions made by thewrapping threads.

The objects of the present invention are:

First, to produce a new and improved packing cord suitable for use inthe millinery trade or the like.

Second, to produce such a cord which is inexpensive, light in weight,and which has a smooth, even surface which will notdisgure a fabricstretched thereover.

Other objects and advantages pertaining to details and economies ofconstruction and operation will appear from the description to follow.

A preferred embodiment of my invention is illustrated which:

Fig. 1 is a perspective view of the core employed in my new packing cordshowing how it is formed.

Fig. 2 is a perspective view of the cord with the wrapping cover open toshow the manner of application thereof.

Fig. 3 is a perspective view showing a section of the finished cord.

The finished cord l is and an outer cover 3.

The core 2 is substantially cylindrical in form and is made up of sheetsof cellulose crepe wadding which is sold commercially under the tradename KimpakJ These sheets are compressed t cylindrical form and theouter covering is applied thereto to hold the core in its form.

in the accompanying drawing, in

made up of a core 2 on the surface of the cordv The outer covering of myimproved cord is made up of a plurality of plies of sheet cellulosecrepe wadding. This material is lace-like in form and apparently has notensile strength. I have found, however,. that a plurality of plies ofthe material form a highly satisfactory cover for a cord such as that towhich this invention relates. The material has considerable tensilestrength and has a very desirable feel in the finished product. It maybe applied to form a smooth outer cover at a minimum of expense. Iprefer t0 employ 10-ply cellulose wadding.

After the core is compressed toform, the covering which consists of astrip made up of a plurality of lsheets of the cellulose crepe waddingis wrapped around the core and the edges are joined by a layer 4 ofadhesive which may be glue or latex. In order to make a smooth core,

I fold the outer overlapping edge 5 inwardly as shown in Fig. 2 andapply the adhesive between the surface of the in-folded edge and thesurface 6 of the inner edge of the cover. The adhesive extends to thesurface of the cord so that a completely smooth covering results.

The nished cord is extremely light in weight and is resilient. Itretains its form even after stretching and is highly satisfactorybecause of these desirable qualities. The smooth outer surface does notdistort the fabric stretched over the cord so that the material does notinterfere with the decorative effects desired in the millinery trade.The material may be made very inexpensively.

I have described and shown a preferred form of my invention and definethe same in the claim.

Having thus described my invention, what I claim as newand desire tosecure by Letters Patent is:

A packing cord consisting of a substantially cylindrical core ofcompressed cellulose crepe wedding, and a smooth outer cover thereforcomprising a sheet formed of substantially 10 or less plie-s of sheetcellulose crepe wadding surrounding said core and retaining it in form,the edges of said sheets overlapping and joined by a layer of adhesive.
